BP ( Back Propagation) algorithm and genetic algorithm are combined into hybrid genetic algorithm of which the algorithm steps are first to locate a favorable searching region by genetic algorithm
then to search optimal coefficients in the located region by BP algorithm. An 100 t arc furnace end aim temperature neural network predictive model is trained respectively by genetic algorithm and hybrid genetic algorithm in this paper. The simulation results show that the hybrid genetic algonthm has faster convergence speed and higher predictive precision
as aim temperature precision is ± 2 ℃
±4 ℃
±6 ℃ and ± 8 ℃
the percentage of hits for aim temperature by standard genetic algorithm is respectively 75%
82%
86% and 92% while that by hybrid genetic algorithm is respectively 80%
